Tin Manufacturing - a brief guide

Tin is said to have been first mined in Turkey. In chemistry, the total number of elements is 118 and tin is the 50th member in the list, being the 14th metal listed in the elements list. The chemical symbol of tin is Sn. The weight of a single tin molecule is 118.710(7)2 mu. Density of a single molecule of tin is 7.287 g/cm2 and the melting point is 505.21 K.

When it is purified, this metal's color will change to whitish silver. Tin is used for industrial purposes such as tin plating and also in the production of fuse materials for electrics. Many useful alloys are made by combining other materials with tin. A common alloy used in industries is an alloy prepared by the combination of tin with copper. Electric solders are manufactured by mixing tin with lead and are used in the manufacturing of pipes and electric circuits. Tin is also used in the production of organo-metallic compounds useful in the preparation of pesticides used in agriculture.

Tin is manufactured by removing the contaminations of tin ore available naturally. By using big tunnels the ore present deep underground is mined. Once the ore is collected from the earth, the pure tin present in it is just 0.5% to 0.75%, and this should be separated from the ore chemically. After this, the bulk of tin collected from the ore is shattered into pieces and then the natural mixtures of stones and soil and other materials are removed. The iron fragments present in the tin ore is removed by using a magnetic source.

After the physical purification, the pure ore is sent for smelting. Now the material is called tin concentrate. The collected tin is put in a furnace with carbon and heated. Carbon monoxide is formed from the carbon by reacting with the oxygen in the fire.

The tin is now available is coarse tin. This is a byproduct of the reaction of carbon monoxide with the tin oxide present in the ore. Another furnace is used and the same method of heating is used and more impurities removed again.

After the smelting process, the tin available is put in another furnace of lower temperature along with slag, a material available sometimes when the tin is heated with limestone and sand if needed. Now the tin is heated to its melting point and so the other materials found can be removed and so that pure tin can be refined and separated.
